Glass is a more expensive material to produce due to the complicated processes involved in its manufacture. Plastic is created by the use of oil as its base. Perhaps, in the current state of affairs and the projected events of the future this will no longer be true. But as of right now, that is why glass bottles are more expensive than plastic ones.
There are capping machines available that make and apply caps to all sorts of glass, plastic and metal containers. There are capping machines for soda bottles, medicine bottles, coffee cans and much more.
Yes, recycling uses more energy than trashing. It takes very little energy to throw steel, aluminium, glass, plastic and paper into a hole in the ground.But to produce more steel, aluminium, glass, plastic and paper takes vast amounts of energy. Almost twenty times as much as what it takes to recycle all these resources. And all these resources are non-renewable. When we have used them all, there's none left!So it is far cheaper to recycle and reuse.
Laminated glass is produced by bonding two or more layers of ordinary annealed glass together with a plastic interlayer, usually polyvinyl butyral (PVB). The PVB is sandwiched by the glass which is passed through rollers to expel any air pockets and form the initial bond then heated to around 70
Using glass as a beverage container has more disadvantages than advantages. While glass is sturdy, it is also very easily breakable and is no longer allowed in many public places, such as stadiums, for this reason.
They are melted down and made into more glass. Thanks
Only aluminum is continually recyclable. Paper has a one cycle recycle life. Plastic costs more in processing and transportation costs than the plastic resins are worth. Household pay more to recycle plastic than it would cost to bury it. Glass is not cost effective to recycle because it costs more to clean and separate it than it costs to make new glass. The energy to make new glass is about the same as recycling used glass.
Glass is more durable.
yes they our since metal costs more to make then plastic. Plastic slinkies cost about $4
Plastic shelving would be better in a freezer than glass because the extreme cold would make the glass more brittle and thus more likely to break.
Glass is more durable than plastic. Plastic is a porous material, which means with absorbs moisture and contaminants. Plastic will also deteriorate when exposed to sunlight. Basically a plastic window would turn yellow and become brittle after only a few years, where a glass window will remain clear and strong for a very long time.
There is no difference in the effectiveness of glass or plastic. Glass is more fragile for breaking but easier to keep clean, plastic is safer for not breaking, and harder to keep clean longer. It is a personal choice.
Yes, both glass and plastic bottles can be recycled, although which kinds of plastic depends on the recycling program in your area. Check out this article for more information: http://kansascity.about.com/od/communityinformation/p/RecycleKC.htm.
I believe so. If you had glass pieces and plastic pieces, and you threw them all in water, the plastic would float while the glas would sink. I hope this helped. ~;]]
Water "wets" plastic more than glass, giving a lower reading
The advantage of plastic is that it is lightweight and more impact resistant than glass. The advantage of glass is that it is scratch resistant and provides the clearest possible vision.
When It comes to decanters, I always prefer glass over plastic. Glass appears more dignified and gives your wine or spirits an extra sparkle.
Steel conduit weighs more, provides more protection, and costs more than plastic conduit. Plastic conduit weighs less, is easier to work with, and costs less than steel conduit.
